29 Jun 381: Joystick Snap fit and static stress with non-linear materials of a joystick and its bearings. The bearings were subject to the snap fit analysis, and used non linear contact and geometry (large deformation) as well as non linear material models. For the snap fit analysis, multiple design iterations were analysed due to stresses being far too high for the initial designs. The final design achieved acceptable stresses. The last 3 design iterations were then subject to a stress analyses, with different bending situations considered. Posted at 11:22h in Read More
29 Jun 383: Rotor Assembly Linear static stress analysis of a rotor assembly. Multiple load cases were analysed with different acceleration loads applied in each case. Wheel loads on the rotor were calculated for each case and applied to the rotor. In all load cases the model passed the acceptance criteria. Posted at 11:21h in Read More
29 Jun 384: Hoist Motor Assembly Linear elastic static stress analysis of a hoist motor assembly, with non-linear surface contact. Beam and solid elements were used in the analysis. In total 9 different load configurations were analysed. For those load cases where the assembly did not meet the acceptance criteria, suitable modifications were recommended.

29 Jun 295: Gangway Linear static stress analysis, including non linear contact, of two gangway designs. The loads included a live load and a wind load for each gangway. Once complete, a buckling analysis was performed using the same conditions. The designs passed both analyses acceptance criteria, confirming the designs viability. Posted at 11:20h in Read More
29 Jun 386: Wheel Motor Assembly Linear static stress analysis of a wheel motor assembly. An initial design was analysed with two different load cases with both vertical and horizontal loads. As well as the factor of safety (FoS) on yield strength, a FoS based on an endurance limit was also reported to cover fatigue. Two further design iterations were analysed based on the recommendations given in the previous analyses. Upon comparison with another new design, it was concluded that the new design was preferable due to much better FoS values. Posted at 11:20h in Read More
29 Jun 392: Stage Platform Corner Assembly Corner assembly consisting of extrusions and castings used for a modular stage platform system, subjected to several load cases. The FEA highlighted issues with the castings and resulted in recommendations for geometric changes. Posted at 11:18h in Read More
